220.127.116.11 Calculation of distribution coefficient
Calculation of distribution coefficient
The maximum stress in the uncracked state is:
We assume a long-term loading:
Taking Tension Stiffening into account, the distribution coefficient is calculated according to the following equation:
- for σmax,φ1 > fctm:
- for σmax,φ1 ≤ fctm:
In the example, the maximum tension stress in the concrete is larger than the concrete tensile strength.
Thus, the distribution coefficient is:
